In a manual material that will help to form skills of verbal account on themes is presented: "Addition and deduction within the limits of 100 with brackets and without brackets", "Addition and deduction of type 239 1, 200-1, 350 20, 460-70", "Increase and division of type 17x3, 51: 3, 51: 17, 126: 14", "Increase and division of type 2x40, 90: 3, 240: 60", "Increase and division of round numbers of type 170x3, 510: 3, 5100: 170,1260: 140". Answering the questions of teacher to each of made examples, students execute a few mathematical tasks - all more than 3000 examples.Successive implementation of tasks of manual will help students to capture skills of verbal account of all forms : by a fugitive auditory account (a teacher reads the chainlet of examples aloud, doing small stops for a count, and a student answers in a few seconds), visual account (the chainlets of examples are writtenin, and answers a student either reports orally or writes down) combined by an account (a teacher dictates the chainlets of examples, and a student writes down answers).Systematic implementation of these tasks develops the logical and mathematical thinking, quick wits, strengthens memory and attention. At discretion of teacher of chainlet of examples it is possible to use both for olympiad works and tasks of enhanceable complication and for a reiteration and fixing of the studied theme. For the best mastering of material it is recommended to decide on ten examples in a day.A manual can be used on the lessons of mathematics and for independent work of house.
